Background
I am working on a WPF windows application and I want add embedded PDF viewer with only basic functionalities including PDF view, text search and page navigation.
I tried embedded Internet Explorer and Adobe PDF Reader installed method (this way ) but this method is not suitable for our requirement as Adobe PDF Reader has too may external links which can not be allowed because of the security reasons of the application.
Therefore, I am trying to use moonpdf library. This library works fine with our requirements but the only problem is there is no text search functionality in this library. (I think it shows PDF as images)
Then, I have download moonpdf source code and realized that moonpdf is using libmupdf.dll wrapping to c#.
I can modify the moonpdf source code and mupdf source code for our requirement if needed.
My Question
Is there any text search functionalities in mupdf? if so how can I use it?
In the basic mupdf library, there are several functions for searching for text. These work by searching a page for a text string, in a few different variants, and returns the area for all hits of the given text. You need to iterate over the pages yourself (in order to do forward or reverse search).
fz_quad hits[1000];
count = fz_search_page(ctx, page, needle, hits, nelem(hits));
That said, I do not know how or even if "moonpdf" has wrapped these functions.
You can certainly extract the text from a document, the MuPDF library will do that. I believe it's up to you to apply your own search criteria after that. I'm afraid I'm not expert enough to answer the 'how to' part of it though. I imagine one of the mutool examples would be helpful here though. I'll see if I can get one of the developers to answer.

I'm trying to find a C# library that will allow me to "Print" one of my HTML pages to a PDF file. I can't seem to find out if one currently exists that will allow you to do this. I've found several that will let you build a page, but haven't noticed if one would generate the pdf only based off of HTML.
EDIT: I'm not allowed a budget on this at work so it will need to be an open source/free product. If not I'm aware of iTextSharp and will have to generate the pdf programmatically (which is what I'm hoping to avoid :) )
I've had a lot of luck with ActivePDF WebGrabber. It's kind of odd to use compared to standard managed libraries (ActivePDF is unmanaged), but it gets the job done.
iTextSharp comes with a little companion : XML Worker
For a demo, have a look here
Even though the documentation refers to the Java API, the adaptation to C# should be straightforward.
I've experimented with itextsharp and it works for basic conversion, but gets complicated when you get into styles and formatting. I've also heard wkhtmltopdf is out there as another option.
I have a PDF and want to extract the text contained in it. I've tried a few different PDF libraries and they all return basically the same results. When extracting the text from a two page document with literally hundreds of words, only a dozen or so words from the header are returned.
Is there any way to tell if the text I'm after is actually text or a raster image of the text? I'm thinking something along the lines of Firebug's "Inspect Element" but at this point I'll take any solution that tells what I'm really looking at.
This project really doesn't justify attempting to use OCR. And, although a simple solution, using fields in the PDF is not an option since the generator of the file is a third party.
If Acrobat/Reader can select the text, then it Is Text.
Reasons your library might not be able to find the text in question:
Complex/bad fonts or encodings. Adobe can be very forgiving of garbage in, somehow managing to get Good Info out.
The text could be in an annotation rather than the page contents. It won't matter what program parses the content stream if you need to look in the annot array instead.
You didn't name a particular library, so it's possible that the library you're using doesn't look inside XObject Forms. That's unlikely in an even remotely mature API, but stranger things have happened.
If you can get away with copy/pasta from Reader, then just go that route.
Have you tried Amyuni PDF Creator .Net? It allows you to enumerate all components from a specified rectangular region of a page and inspect their type from a predefined types list. You could run a quick test using the trial version and the following code sample for text extraction:
// open a PDF file
axPDFCreactiveX1.Open(System.IO.Directory.GetCurrentDirectory()+"\\sampleBookmarks.pdf", "");
axPDFCreactiveX1.Refresh ();
String text = axPDFCreactiveX1.GetRawPageText (1);
MessageBox.Show (text);
Additionally, it provides Tesseract OCR integration in case you needed it.

Given an existing PDF document, I would like to tack on an index to the end of the file to show the pages on which key words show up. It would be best if I don't have to give a list of words to look for and the list of words is automatically generated. However, if a list of words must be given, I can work with it. I'm looking to do this either through a C# library or a command line tool. It needs to run as part of another command line app.
Is there anything out there that is capable of this?
This "PDF Index Everthing" (http://www.pdfstore.com/details.asp?ProdID=799) seems to be on the right track, but requires interaction through its GUI.
I don't actually have an c# solution but hopefully this will still help...
pdflib is an excellent pdf development library. It is one of the better libs available. As far as I know it doesn't have a C# binding. PDF is a random access object-based file format and although there are many libraries that allow for creating of pdfs, most freely available libs don't support adding pages to existing pdfs. pdflib does support adding pages with it's pdi option, so it may be worth checking out.

I have been searching for several hours but i couldn't find anything about this... Basically I would like to create a template or plug-in for word 2007 that would allow someone to create new pages for a CMS. What I have in mind is something similar to blog post template. I know how to create a basic template but I can't find a way to publish the created document using a publish button inside the Word.
thnx in advance
I understand what you are trying to achieve, but Word is the wrong starting point. I would start with a much more basic text editor.
Word is horrible, horrible, horrible. Your site will define clear styles, yet Word will output nasty HTML that won't match your website's CSS definitions.
Your best bet therefore is to have a means to drop the Word file into the site, and have code programmatically analyse it and transform it into site-valid HTML. In Java you could use Apache POI, but that's very raw still. Might be a lot easier in a Microsoft centric world.
Far better, in my opinion, is to force people to learn Markdown, or BBCode, or HTML, or to use a Styled HTML Editor in your CMS - cut and paste plain text in, then style with the CMS defined styles.
As you are using Word 2007 you can export the document as XML and then use XSLT to generate the HTML.
If your CMS has an API or import facility you could convert the output from Word to suit that interface.
You can write a Word macro to add a Publish button/menu option to Word that will generate the correct output.
It's not a bad idea since it's all about the end user. If Word produces bad HTML, you should just make it semantic correct before posting it to the CMS.
I've never done this but I'm sure that it's possible to with .NET via the "Word 2007 Addin"-template (assuming Office 2007).
Good luck!
You can do what you want if you use SharePoint 2007 as your CMS. You can set up a blog on SharePoint 2007 and post to the blog from Word. If you use Office 2007 on the client end then you will get some nice buttons like "post to my blog" etc.
If you can't use SharePoint or are talking about an existing CMS, you have a lot of hurdles to jump through. This is a major undertaking and not something you can get a simple answer out of Stack Overflow.
Have you considered using one of the freely available Javascript WYSIWYG Editors such as TinyMCE http://tinymce.moxiecode.com/? When configured with all the options, it has an impressive amount of functionality and the interface is very similar to Word. I realize this doesn't directly answer your question, but as others have pointed out starting from Word is going to be difficult.
I've been on a team that wrote a Word addin for a custom CMS system. It was written in VB6 and was able to take a Word document and turn basic formatting information - lists, bold, italic and even tables into HTML, which was uploaded to the server. It didn't create new pages or manage the site in the addin though.
I would definitely avoid choosing Word as the editor for your CMS from my experience. The biggest issue is each time you want to update the addin you have to redistribute it to the company or companies using it. You can do this is as an IE active-x control but it's far easier just to handicap the user to a limited set of styling options via a Javascript editor.
Word does have a powerful API for manipulating your content with, however we needed to disable so many options in Word to avoid unwanted fonts and so on, it resembled Wordpad more than Word in the end.
If it's a greenfield project and you have the time, I would infact recommend using Silverlight 4.0 over a Javascript editor. Version 4.0 has a richtextbox control built in, plus there is also the excellent Vectorlight one.
May be it helps you, umbraco CMS allow editing with Microsoft Word.
For some reason this is a feature that Excel enjoys but not Word.
Excel can can automatically publish an HTML file version of your document when you save it.
Unfortunately Word seems to only be able to achieve this functionality when using Sharepoint, which is a shame because it can be quite useful.
What you can do, short of creating your own add-in is to add a bit of code to your template to create a HTML copy of your document whenever the user saves it.
First, make sure your template is macro-enabled (saved as .dotm file).
Second, while editing the template in Word, open the VBA code editor (ALT-F11)
In the project list double-click on your document to open its code-behind file.
Add the following bit of code to it, modifying the ActiveDocument.SaveAs path to something more appropriate to you, like a shared network folder where your CMS exposed by your CMS.
Sub FileSave()
' First Save the main document
ActiveDocument.Save
' Now we create a new document based on the current one
Selection.WholeStory
Selection.Copy
Documents.Add
Selection.PasteAndFormat wdPasteDefault
' Save it as HTML and close it
ActiveDocument.SaveAs "c:\temp\mydoc.html", fileformat:=wdFormatHTML
ActiveDocument.Close
End Sub
This will copy the original file into a blank new one that will be saved to HTML and closed before returning to the original file.
You can check some of the options to the Documents.Add if you want to use a different template than the normal one.
Security
because this template contains macros, you will have to install it with the other templates where Word expect them.
If you don't, then you'll get a security warning.
To avoid getting it, you can add the path where your templates are located to the list of Trusted Locations under Word's Options > Trust Center > Trust Center Settings > Trusted Locations.
I`d like to be able to read the content of office documents (for a custom crawler).
The office version that need to be readable are from 2000 to 2007. I mainly want to be crawling words, excel and powerpoint documents.
I don`t want to retrieve the formatting, only the text in it.
The crawler is based on lucene.NET if that can be of some help and is in c#.
I already used iTextSharp for parsing PDF
If you're already using Lucene.NET you might just want to take advantage of the various IFilters already available for doing this. Take a look at the open source SeekAFile project. It will show you how to use an IFilter to open and extract this information from any filetype where an IFilter is available. There are IFilters for Word, Excel, Powerpoint, PDf, and most of the other common document types.
There is an excelent open source project POI, only drawback - it is written for Java.
The .net port is somehow very beta.
Here is a good list of various tools for converting Word documents to plaintext, which you can then do whatever with.
Here's a nice little post on c-charpcorner by Krishnan LN that gives basic code to grab the text from a Word document using the Word Primary Interop assemblies.
Basically, you get the "WholeStory" property out of the Word document, paste it to the clipboard, then pull it from the clipboard while converting it to text format. The clipboard step is presumably done to strip out formatting.
For PowerPoint, you do a similar thing, but you need to loop through the slides, then for each slide loop through the shapes, and grab the "TextFrame.TextRange.Text" property in each shape.
For Excel, since Excel can be an OleDb data source, it's easiest to use ADO.NET. Here's a good post by Laurent Bugnion that walks through this technique.
You might also consider checking out DtSearch (www.DtSearch.com). Although it is primarily a searching tool, it does a great job of extracting text from a large number of file types and is considerably cheaper than other options like the Oracle/Stellent OutsideIn technology or the equivalent from Autonomy.
I've been using DtSearch for years and find it indispensible for this type of task.
